Determining Star Formations Rates: Methods and Uncertainties
نویسنده
چکیده
Methods for the determination of star formation rates (SFR) from integrated populations are reviewed. We discuss the assumptions and underlying uncertainties (e.g. IMF slope, Mup, metallicity, SF history etc.) used in the calibrations of UV, FIR, Hα, and [O ii] λ3727 indicators. The “universality” of empirically calibrated indicators such as [O ii] is examined. We also present preliminary results from a theoretical study with the aim to understand the systematics of forbidden line indicators and to provide new SFR indicators including optical to far-IR lines.

Uncertainties in Evaluation of the Sediment Transport Rates in Typical Coarse-Bed Rivers in Iran
Flow and sediment transport processes are different and more complex in coarse-bed rivers than in sand-bed rivers. The main goal of the present study is to evaluate different modes of sediment transport using different hydrometric and hydraulic methods, and to address the major uncertainties. Four river reaches were selected as representatives of coarse-bed rivers in the Northwest of Iran. A se...
متن کاملStar-formation as a cosmological probe
We discuss the cosmological dependence of the star-formation history of the universe, within the framework of a very simple semi-analytic model, where star-formation occurs within the virialized cores of dark matter halos, at a rate which is primarily governed by rate of matter infall into the halo core. Our model is extremely simple, contains a number of uncertain features, and cannot be expec...
متن کاملAssessment of formations erodibility through reagent alluvial sediments morphoscopy (Case study: Sajjadrud basin)
Erodibility of basin formations is depends on their resistance versus of erosion. In a basin are not the same stones, their resistance and covering area. Obviously, formations sensitivity versus of erosion are determining rate of sediment production in a river. In this research has been analysis formation erodibility versus of erosion in the Sajjadrud basin. Research methods are descriptive–ana...
متن کاملXiangshun Li Control for Formation of Multi-Agent Systems with Time-varying Delays and Uncertainties based on LMI
In this paper, robust stability of vehicles formation system with structural uncertainties and time-varying delays are analyzed. The vehicles are modeled as general linear systems and the feedback control is based only on relative information about vehicle states in an undirected communication topology graph. Sufficient conditions are proposed for asymptotical stability of vehicles formations s...
متن کاملAnalysing observed star cluster SEDs with evolutionary synthesis models: Systematic uncertainties
We discuss the systematic uncertainties inherent to analyses of observed (broad-band) Spectral Energy Distributions (SEDs) of star clusters with evolutionary synthesis models. We investigate the effects caused by restricting oneself to a limited number of available passbands, choices of various passband combinations, finite observational errors, non-continuous model input parameter values, and ...
